You didn’t post the full traceback, but I can take a guess: You set seq equal to the method stepper.clockwise on the first line.

Nothing, because: You shouldn’t use clockwise … Read more

This traverse generator function can be used to iterate over all the values:
The problem might have to do with the fact that you are adding ints to strings here As far as I’m aware, the interpretor cannot implicitly convert an int to a string. This might work, though, On which I’m assuming Python > 3.0

For the “correct” way see the order keyword argument of numpy.ndarray.sort However, you’ll need to view your array as an array with fields (a structured array). The “correct” way is quite ugly if you didn’t initially define your array with fields… As a … Read more
I’m fairly new to Python and NLTK. I am busy with an application that can perform spell checks (replaces an incorrectly spelled word with the correct one). I’m currently using the Enchant library on Python 2.7, PyEnchant and the NLTK library. The code below is a class that handles the correction/replacement. I have written a … Read more
Your factorial() function returns 0 for any input because of how you defined your range. The range builtin starts at 0 unless otherwise defined so: is doing: on the first iteration so for all subsequent iterations: will always be 0 Start your range at 1 like so you can see this more explicityly: or instead … Read more
2018 Update: As of February 2018, using compressions like gzip has become quite popular (around 73% of all websites use it, including large sites like Google, YouTube, Yahoo, Wikipedia, Reddit, Stack Overflow and Stack Exchange Network sites).If you do a simple decode like in the original answer with a gzipped response, you’ll get an error … Read more
The preferred method is to use NGINX or another web server to serve static files; they’ll be able to do it more efficiently than Flask. However, you can use send_from_directory to send files from a directory, which can be pretty convenient in some situations: Alternatively, you could use app.send_file or app.send_static_file, but this is highly … Read more
